Definitions

  • This invention relates to resilient seatings for easy cha1rs, settees or vehicles (hereinafter referred to as chairs), of the type wholly or mainly employing tension p ngs;
  • the invention consists in a resilient seating structure comprising an upper deck of canvas or other flexible materlal .of an outline congruent with the shape of. the chair framing in the region of the seating plane, supported at theedges on tension springs arranged more or less parallel with the seat framing and anchored to said framing; a lower .deck of convas or other flexible material spaced vertically fromand'preferably of sub stantially less area than the upper deck .to aiford re-.

  • Figures 5 to 9 are partial plan views of various modified forms of the seating showing various alternative arrangements of the springs supporting the lower deck.
  • Figure 10 is a partial plan view of a further modified form of the seating showing an alternative arrangement of the lower deck and the springs supporting the same.
  • the resilient seating of the chair 1 is formed by two spaced decks of canvas or other flexible but inextensible material disposed one above the other to form an upper deck 2 and a lowerdeck 3.
  • Each deck isindependently supported within the area defined by the chair framing structure in the region of the seating plane l and formed by side members 4 by tension springs 5 and 6 anchored to brackets 7 secured to the chair at or adjacent the corners of said framing structure.
  • the brackets each have a of spaced arms or lugs 7a and 7b adapted for receiving, or attachment to, the ends of the ⁇ deck supporting springs and each bracket is secured to the framing structure with one of the lugs thereon re,
  • each bracket lies substantially in the plane of the upper deck 2 and the lower lug 7b lies substantially in the plane of the lower deck 3.
  • the area and outline of the upper deck 2 is generally congruent with the shape of the chair frame structure in the region of the seating plane and a tubular pocket or "seam 8 is provided at each of the four marginal edges of the deck each to receive a tension spring 5 formingpart of the resilient support for the upper deck.
  • Each spring 5 extends through its respective pocket 8 generally parallel and closely adjacent to a side 4 of the seat frame structure and its ends are anchored to the uppermost lugs 7a of two of the corner brackets 7.
  • the upper deck 2 is thus supported at the edges by four tension springs 5 and the tension in these springs is such as to exert a pull on the upper deck tendingtotighten and stretch the same across the area defined by
